Peppol E-Invoicing Without the PKI: Sending Invoices with One API Call

Peppol means BIS 3.0 UBL, Schematron validation, AS4 transport and certificates. How e-Gate turns all of that into a single JSON request, for the UAE and beyond.

e-Gate API request that sends a Peppol e-invoice as JSON

Peppol is the network behind e-invoicing mandates in Belgium, Germany, France, Singapore, the UAE, Oman and more. Joining it directly means producing UBL documents, running validation rules, holding certificates and transmitting over AS4. e-Gate, our Peppol service, takes that work off your team.

How it works

  1. Sign up and issue an API key. Test keys point at a sandbox, so you can test end to end without real traffic.
  2. POST your invoice as JSON: line items, totals and the buyer's Peppol participant ID. The payload is the same for every country.
  3. e-Gate maps it to Peppol BIS 3.0 UBL, validates it against the official OpenPEPPOL Schematron rules, then signs and transmits it via AS4 to the buyer's Access Point.
  4. You get the receipt: status webhooks on every change, and signed AS4 receipts kept in your archive.

What you no longer have to manage

  • Certificates: Access Point credentials live in our vault, and we sign with our certificate
  • Country rules: XRechnung, FR CIUS, SG Peppol, PINT-AE and PINT-OM are handled server-side
  • Validation: failures are parked for human review, never silently dropped
  • Inbound invoices: they arrive parsed into the same JSON shape you use to send

An audit trail you can prove

Every transmission is recorded in a per-tenant SHA-256 hash chain, so you can show what was sent, when, and that it hasn't changed.

Why the UAE matters

The UAE's national e-invoicing runs on Peppol, with Phase 1 for large taxpayers from July 2026 under the FTA-published PINT-AE rules. Bytize Technology Solutions LLC is an OpenPeppol member, listed in the UAE as an Access Point Provider and an SMP Provider.
